The Siemens EN-PAD (part number 310-099073) is the black enclosure for the PAD-3 distributed power supply. Specifically, it is the sheet-metal cabinet half of a complete Siemens PAD-3 NAC extender. Combine it with the PAD-3-MB main board (500-699080) to form a full PAD-3 unit.
The PAD-3 expands notification appliance circuit capacity on Siemens fire alarm control panels. Therefore, the EN-PAD is the right order when an existing enclosure is damaged or repainted. Alternatively, order the complete PAD-3 (599-699189) if you need board and enclosure together.
Siemens EN-PAD in the PAD-3 Series
Per the Siemens PAD-3 datasheet, the series breaks down as follows. First, PAD-3 (599-699189) is the complete extender with black enclosure. Then, PAD-3R (599-699190) is the same unit in red. In addition, PAD-3-MB (500-699080) is the main board alone. Finally, EN-PAD (310-099073) and EN-PADR (310-099150) are the black and red enclosures.
